I just started up my car after swapping out a plate in the vortech fmu and tightening up the bolts inside of it a bit. They were loose and after calling up vortech it seemed like the proper thing to do. But now my fuel pump is whining.

my question is do you think it's going out or that the vortech's completely blocking the line now??

 

do u have a walbro? mine whined crazy loud...because it's right there next to you.

 

nah it's a gsx pump. I'm not sure what it's doing. I'll hook up the wideband tomorrow and see if it's running super rich now or something.

 

my gsx pump has always been crazy loud... let me know if anything changed! lol

 

Higher flowing pumps whine more. Especially on a low tank of gas.

 

my gst pump whines

i just raise the radio when i drive lmao.gif

 

huh, but I thought being a stock pump it wouldn't do that. and it hadn't whined up until this point. had it in there for months.

and yes it is low.

 

my gsx doesn't whine at all

wich pick up (sock) did you use?

 

you gotta use the stock hyundai sock to prevent fuel slosh from starving your pump during cornering at lower then 1/4 tank... also they are gonna whine how do u think its moving more gas?

 

I wouldnt worry about it, have you ever heard GMs old Fuel pumps?
they sound like this WHAAAAAAAAAAAA!!!!!!
